Co-Enzyme Q10 is not only good for heart, but also against Cancer

CoQ10 supplementation appears not to be completely safe for breast cancer patients and survivors. A deficiency in CoQ10 appears to increase breast cancer risk, however high levels may promote breast cancer. See "Plasma coenzyme Q10 levels and postmenopausal breast cancer risk: The Multiethnic Cohort Study" published in 2010, which found that U.S. postmenopausal women in the highest third of circulating CoQ10 levels had 1.6 times the risk of breast cancer compared to those in the lowest third. More work needs to be done on this, but caution is advisable, I think.
